new freeware to visualize single-string beats and inharmonicity

[R Barber]

Piano techs with Macs & OSX:

Inharmoviz is a very very small program that visualizes the note A1, as 
measured by my Verituner 100, on four pianos (9', 7', upright, and 
spinet).  The software recreates the tone digitally and displays it in
three visual manners.  The result is a display of the beats present in
single piano strings, and a way to compare the relative instability 
among the four sizes.

It's cost-free and virus-free. Inspired by this afternoon's thread on 
pianotech, I compiled it this evening using Cycling 74's Max/MSP. 
Enjoy!  Sorry I don't have the Windows compiler.  If one of you do, I'd 
be happy to send you the abstraction.
